It's been raining like crazy lately and I've been able to use it lots! Awesome little thing!
going to try as mine is faulty now.
now what stops this from working in mk1's? different relay spots? I have an mk3 wiper motor..... shouldnt it work

lol
I beleive it works on the later mk1 style fuse boards. I've got an '83 MK1 GTD and replaced the 19 by a 99 and it works great. Also swaped the 21 (or is it 20) by a 72 and now have intermittent rear wipers too
